I’ve had a blast figuring out when photos in Dad’s collection were taken from looking for clues, like magazine covers, where even if I can’t read a legible date, I can see enough of a cover to find it in back issue archives. This is maddening, because there’s a freakin’ calendar on the wall, but it’s illegible, and there were a billion wall calendars, so I can’t go searching. Oh well, I guess I just have to leave it at “mid-1950’s.”
